For all the key elements in a medical record history, physical findings, test results, etiology, exposures, severity scales and scores, discharge diagnoses, and outcomes healthcare providers differ in how they observe, measure, interpret, and report their findings [ 26].
Timing and amount of drug exposures were considered, and biologic measures of exposure were quantified to classify exposure severity.
The standards would tighten depending on level of hazard determined through a "fire exposure severity zoning system".
The experimental results indicated that increasing the thermal exposure severity and duration increased the breathing air temperatures supplied by the SCBA.
The striking heterogeneity that exists between experimental studies may be explained by differences in subjects (e.g., species, strains, genetical modification, age, sex), and exposure (e.g., pre-exposure, severity, duration, anesthesia, ventilation).
Assessment of severity of exposure Severity of exposure is assessed only for drugs and alcohol using the maximum daily dose recommended for drugs (a therapeutic index >1 denotes an intoxication) and a blood alcohol level (BAL) of 0.4 g/l (a BAL > 0.4 g/l was considered toxic).
Trauma-exposure severity in controls will be assessed as lifetime.
Strangely, though, differences in exposure severity do not appear to account for observed inconsistencies.
Trauma-exposure severity will be operationalized using data from the BTQ, 2001 Violence Questionnaire, and updated adult violence exposure.
Figure 1 shows the frequency of reported nightmares and flashbacks in the five sub-samples grouped by exposure severity.
Once cases are selected, we will stratify them based on current age (42 51, 52 62), ethnicity, and trauma-exposure severity.
